通过超声辅助溶剂热法制备一种新型的二维类复合光催化剂BiOCl/MOF-5.运用XRD、SEM、BET、TEM、PL等手段对催化剂的特殊结构和性能进行表征.在该光催化剂体系中,选取MOF-5为载体,通过与光催化剂BiOCl复合来合成一种新型的二维复合光催化剂.结果表明,制备的催化剂均呈现出较为明显的二维结构形貌,且相对于单一BiOCl(3.15 m2·g-1)来说,该复合催化剂(110.16 m2·g-1)的比表面积得到了明显的提高.由于催化剂的光催化性能与其比表面积和孔隙体积密切相关,复合催化剂相对较大的比表面积和适当的能带隙,有利于为反应物提供更多的活性位点和有效的传输路径.得益于MOF-5独特的形貌和结构,光催化剂聚集和比表面积小的问题也得到了解决.因此,该复合材料在降解有机污染物方面呈现出优异的光催化活性,且与纯BiOCl相比,催化剂的光催化活性得到了明显的提高.

基于密度泛函理论,采用广义梯度近似(GGA+U)平面波超软赝势方法,计算了本征GaN和稀土元素Lu、Sc掺杂GaN体系的电子结构和光学性质.结果表明:计算得到本征GaN的禁带宽度为3.37 eV,与实验值(3.39 eV)接近. Lu掺杂后GaN体系带隙变窄,而Sc掺杂后诱导了深能级杂质,带隙变宽,但仍为直接带隙半导体.掺杂后体系均发生畸变,晶格常数和体积增大,且在费米能级附近产生杂质带. Lu、Sc掺杂GaN体系的静态介电常数较本征GaN(4.50)均有所增大.Lu、Sc掺杂后体系介电常数虚部整体左移,光吸收边往低能方向移动,发生了红移现象.计算结果对稀土元素Lu、Sc掺杂GaN高压光电材料的开发和研究提供了理论依据.

为探究酸性稻田土壤中铜(Cu)和硫(S)共存对温室气体排放的影响,本研究模拟土壤淹水环境开展室内培养实验,以尿素为氮源分别设置CK、CuCl_(2)和CuSO_(4)(5,50,100mgCu/kg)、KCl和K_(2)SO_(4)(阴离子浓度分别与6种Cu处理一致)13种处理,考虑重金属在土壤中充分老化,共培养128d.结果表明:在长期淹水条件下,酸性土壤显著促进铜硫处理中有效Cu和易溶S释放(0.05).与CuCl_(2)处理相比,CH_(4)和N_(2)O排放在中、高浓度CuSO_(4)处理中显著降低(<0.05),分别减少46.0%、66.0%和17.7%、37.3%.Cu-S作用机制表现为:与Cu单一处理相比,Cu-S共存在CH_(4)排放过程中通过降低产甲烷古菌功能基因(mcrA)和产甲烷细菌功能基因(16S rRNA-CH_(4))丰度减少CH_(4)产生;在N_(2)O排放过程中于培养前期(0~35d)增加氨单加氧酶功能基因(AOB amoA)丰度促进硝化过程N_(2)O产生,培养后期(35~128d)提高氧化亚氮还原酶功能基因(nosZ)丰度促进N_(2)O还原减少了N_(2)O排放.本研究表明变价阴离子可显著影响重金属阳离子参与的温室气体产生的微生物过程,该交互过程的研究对正确评价重金属污染背景下的农田土壤温室气体排放具有重要意义.

肺癌是全球发病率和死亡率最高的恶性实体肿瘤类型之一,近年来肺癌生存率有所提升,但其预后及5年生存率仍然欠佳。肺癌的危险因素包括吸烟、环境污染、职业因素、慢性阻塞性肺疾病等。烟碱型乙酰胆碱受体(nAChRs)形式多样,且广泛参与机体的生理、病理及药理过程,烟草中主要成分之一——尼古丁进入人体后,可由nAChRs介导产生作用。研究发现不同亚型的nAChRs存在单核苷酸多态性(SNP),且可对其功能产生影响。全基因组关联研究(GWAS)作为流行病学的研究策略,可更好地挖掘出与癌症发生密切相关的SNP位点,进而使寻找与癌症发生发展密切相关的靶标和药物成为可能。基于国内外相关研究成果,本文从肺癌的全球流行情况、nAChRs相关基因SNP及其功能与肺癌的关联研究等进行系统阐述,以期为肺癌的精准预防及治疗提供参考依据。
